Default Random single beeps from motherboard while running Windows

For the past few months my motherboard has been emiting single long
beeps while running Windows. It's really driving me nut that I can not
figure out what's causing this.
Specs:
Foxconn 945P7AA-8EKRS2
Chipset: Intel® 945P + Intel® ICH7R
Processsor:: P4 Prescott 800MHZ FSB
Ram: 2 Kingston 1GB DDR2 667
Video Card: SAPPHIRE 100164L Radeon X1650PRO 256MB 128-bit GDDR3 PCI
Express x16 CrossFire Supported
BIOS ID: Phoenix-Award
BIOS Date: December 15th 2005
BIOS ID: 12/15/2005-LakePort-6A79HFKCC-00-None
BIOS OEM: i945 Series 515F1P38 121505 - 6.00 PG
Chipset: Intel 2770 rev 129
SuperIO: ITE 8712F rev 7 at port 002E
OS: Windows XP Pro, SP 2 with most of the available security patches
installed.
3 internal sata drives, 1 floppy, 1 dvd burner. 500 watt PSU.
I built this machine in January 2007.

The pc boots fine and only emits the single short beep at post. It will
run for days without beeping. Yesterday I had it on for about 2 hours
before it beeped.
It will beep when it's doing absolutely nothing, running the screensaver
or transfering files,
I took the side panel off the case thinking the problem might be heat
but it still beeps. The case has 2 good fans and I installed a huge heat
sink fan on the processor.
The bios is set to monitor the cpu temp and shut the machine down before
it gets too hot.
I've run Memtest + and Windows Memory Diagnostic on the ram, no
problems found.
I've tried looking up the beep tones for the bios but I can't tell if I
should be looking at Award or Phoenix codes. Also, I'm not getting
error tones on post but while to OS is up and running fine. I can't find
anything in the Widows Event viewer that's of any help either.
I've used PC Wizard and Everest Home to look at the hardware and both
report the the board has no battery. It does have a battery and I have
no symptoms of battery problems. The time/date is always correct, the
machine hangs on to the bios settings between boots.
I have SOME minor problems with this machine: it seems slow while
logging on even though I've cleared out the prefetch folder a few times.
It's slow to log off and shut down. I get frequent shell crashes
especially when moving video files. I can't drag and drop to the recycle
bin, the pc freezes and the cursor vanishes, I have to use the "delete"
key.
I'd like to be able to use this machine to re-encode video. I have a big
collection of vhs I'm trying to transfer to dvd. I can't do this now
because i dare not leave this pc running unattended. Should I just bite
the bullet and buy another motherboard while there are still a few
available that support the rest of my hardware?
Any ideas, hints, tips, suggestions?

manual here

http://www.foxconnchannel.com/suppor...D=en-us0000001

says Phoenix - Award bios...which is not real helpful

Even though your RAM did not fail the test...
I'd try some different RAM
or run it on one stick at a time if possible

The BIOS ID is right in your post above: BIOS ID: Phoenix-Award. It's
an Award BIOS.
Award BIOS beep codes here,
http://bioscentral.com/beepcodes/awardbeep.htm ,

indicate a CPU overheating problem. Your description of the system
running slow, etc. could be due to the CPU being throttled back to a
slower speed when it gets too hot. If I recall, P4s were known for
getting very hot.

I would remove the heatsink, clean it and the CPU really well and
reinstall the heatsink with a THIN layer of heatsink compound. Also,
make sure the rest of the inside is cleaned out.

If that is not the problem, or you are absolutely certain the CPU is not
overheating, I would suspect the power supply is going bad. Check all
the power connections and make sure there are no signs of burned, or
melted pins. Check the voltages at the ATX connector with a DVM and
make sure they're all within tolerance (+-5% of the proper voltage).
Don't forget the extra +12V connector for the CPU if your MB uses one.

I think I'm getting the "repeating high/low they mentioned. My P4 can
take up to 67c, it usually runs at about 30c.

I put a huge heat sink on this thing:
http://www.neoseeker.com/Articles/Ha...ttgoldenorbII/
I'd have to take the board out of the case to get it off the processor.

I found a couple apps that measure the temperature of the video card and
mine was running REALLY HOT! I took the heat sink off that and re-
applied thermal paste. Dropped the temp on the card 10-15 degrees. I
wonder if it was baking the cpu with all the heat comming off it.
Added a pci slot fan to pull more heat out of the case and away from the
card and CPU. Will have a friend test the power supply with a meter this
weekend.
Thanks everybody.

Not the Golder Orb!! I remember that heatsink/fan and it wasn't known
for being very efficient at all, although I didn't know they made one
that large!

It's possible the extra heat from the video card was making the CPU temp
artificially high. It's good that you've got the temp down. Good case
air flow is also very important.

Also, make sure the fan on the CPU heatsink is spinning as fast as the
MB expects. If the fan slows down while the system's running, it can
lead to high CPU temps and/or you may be getting an alert that the fan
is too slow. Check in the BIOS for settings for CPU fan speed and alert
threshold settings.

Make up your mind. You either remeber "it" or you don't.

There were many 'Orbs" made by Thermaltake, quite a few of them golden. The
original Golden Orb was pretty much the forerunner of affordable
after-market CPU heatsinks and was considerably more efficient than Intel
HSFs of the time. Tt lost the plot with the orb range a bit when other
manufacturers came along and gave competition, producing some very niosy and
some not-so-great models. However, the original was a great cooler. The
Golden Orb II is, like the original Golden Orb, a reasonably-priced
after-market HSF that is better at cooling a CPU than the standard (at the
time) Intel HSF.

Sure, it ain't up to the standards of some of today's coolers but it's an
improvement over stock on an old Prescott.

I found a couple apps that measure the temperature of the video card
and mine was running REALLY HOT! I took the heat sink off that and
re- applied thermal paste. Dropped the temp on the card 10-15
degrees. I wonder if it was baking the cpu with all the heat comming

lead to high CPU temps and/or you may be getting an alert that the fan
is too slow. Check in the BIOS for settings for CPU fan speed and
alert threshold settings.


The Tt golden Orb fan runs at 1.5K rpm standard so you could be onto
something there. If there is a BIOS routine enabled that adjusts CPU fan
speed that could be a possible cause of the beeping. You shouldn't use a
'variable' setting with a cooler like the Tt GO II, it's quiet enough at
it's default speed.

Another thing to consider is northbridge temp, although one would think with
that Tt throwing air 360° it should be keeping the NB cool.
